GOES Rebroadcast Service (GRB)

• Provides full resolution products from all instruments– All data will be calibrated and navigated (“Level 1b”)– Some products, such as the GLM, are higher level products

(“Level 2+”)

• Replaces current GVAR service– 31 Mbps in GRB versus 2.1 Mbps of GVAR– DRO receive systems specified for same size antennas (G/T of

15.2 dB/K), however with significant changes:• Dual polarization (feed changes and dual receiver chain)• High-level modulation (e.g. QPSK, OQPSK, or 8-PSK (TBD))• Forward error detection coding (Low Density Parity Check

(LDPC) (TBR)) to reduce required C/No

28

GRB Dual Polarization Characteristics

• Currently the L-band frequency spectrum of 1683 MHz to 1698 MHz is available for use by Geostationary Meteorological Satellites– As such it is a protected resource for the user community– Obtaining new frequencies anywhere in the RF spectrum is extremely

difficult so maximizing the utilization of this resource is necessary

• Dual Polarization is a well known technique for doubling the capacity of satellite channels– Notably at C-band for television distribution– No dual-polarization utilization data is available for the L-band frequencies

currently used by weather satellites (1600-1700 MHz)

• GOES-R program research indicates GRB will meet availability requirements under almost all conditions with margin– Extensive testing at the Wallops, VA Command and Data Acquisition

Station characterized cross polarization effects for L-band dual circularly polarized links

30

Other GRB Service Design Considerations

• Modulation type, coding and other link characteristics to be defined by Spacecraft contractor in conjunction with Government and Ground contractor through an Integrated Product Team (IPT)– DVB-S2 link characteristics and compatibility under consideration

• Data formatting and product details to be defined by the GOES-R Ground Segment contractor in conjunction with GRB IPT; but will have – CCSDS packetization– Data types segregated between polarizations

• LHCP to provide subset of imagery (0.64, 3.9, 6.185, 7.34, 11.2, 12.3, 13.3 micron channels);

• RHCP to provide remaining 9 channels, plus all other instruments.

31

Emulated GVAR (eGVAR)

• GOES-R will provide a limited capability to produce emulated GVAR (eGVAR) Imagery to Users capable of receiving today’s GVAR data stream– Relies on availability of a spare satellite from the GOES N/O/P series to

broadcast to users.– Transmitted signal will have GVAR characteristics:

• Same transmit frequency and power levels• Same GVAR format• Five channels from the ABI (0.64, 4.9, 6.19, 11.2, 13.3 µm)

– Similar to the GOES Imager channel wavelengths • Imagery will be mapped to GOES N/O/P resolution• No Sounder data • Limited to Full Disk scenes on the half-hour

– No Mesoscale data

HRIT/EMWIN

• Individual Low Rate Information Transmission broadcast (LRIT) and the Emergency Managers Weather Information Network broadcast (EMWIN) combined onto common carrier

• Provides growth path for both Services to a combined 400 Kbps information rate

– LRIT currently 128 Kbps information rate

– EMWIN currently: 9.6 Kbps (GOES 11&12), 19.2 Kbps* for GOES 13-15.

• Will utilize BPSK modulation w/ convolutional and Reed-Solomon coding

– Same as LRIT, but higher data rate

– Allows maximum EIRP from satellite due to Power Spectral Density restrictions

– EMWIN Users modulation type changes from uncoded FSK (GOES I-M), from coded OQPSK (GOES-NOP) to coded BPSK

35

HRIT/EMWIN (Cont.)

• Name change to High Rate Information Transmission (HRIT) required by CGMS categorization of services

• Virtual Channel Data Units used to separate EMWIN and LRIT data:– Virtual channels used in LRIT today

• Prototype Software Defined Radio developed and demonstrated by Aerospace Corporation

– One hardware/software configuration can receive all current and future EMWIN, LRIT and HIRT/EMWIN signals

– Technology demonstration to proves low cost, PC-based terminals are possible for all data rates and modulation types

GOES-R Instrument Suite

04/19/2343

 The GOES-R instrument suite will offer new direct broadcast data types and products from a enhanced suite of on-board instruments, observing atmospheric, ocean, land, lightning, and space weather. 

ABIThe Advanced Baseline Imager (ABI) is a multi-channel (visible through infrared) passive imaging radiometer designed to provide variable area imagery and radiometric information of the Earth’s surface, atmosphere and cloud cover.  The ABI provides moderate spatial and spectral resolution at high temporal and radiometric resolution to monitor rapidly changing weather. ABI is designed to measure solar reflected and emissive radiance simultaneously in 16 spectral channels. The ABI can complete a full Earth disk scan in 5 min and a 1000 x 1000 km mesoscale scan in 30 sec.GLMThe Geostationary Lightning Mapper (GLM) will detect the frequency and location of lightning activity. The GLM instrument will not directly produce images, but will provide event data to the ground system, which will use spacecraft telemetry, orbit and attitude information and other data to generate calibrated and navigated products mapping lightning discharges over the hemisphere.SUVIThe Solar Ultraviolet Imager (SUVI) provides narrowband imaging in the soft X-ray to EUV wavelength range at a high cadence. It replaces the current GOES-M/P series Solar X-ray Imager (SXI) instrument and represents a change in both spectral coverage and spatial resolution over the SXI. EXISThe Extreme ultraviolet and X-ray Irradiance Sensor (EXIS) comprises two distinct instruments. The Extreme Ultraviolet Sensor (EUVS) is a full disk FOV (40 arc min) detector measuring integral solar EUV flux. The X-ray Sensor (XRS) measures the full disk integral solar X-ray flux and will monitor the duration and magnitude of X-ray flares. The EXIS and SUVI are mechanically integrated on a common Sun-pointing platform.SEISSThe Space Environment In-Situ Suite (SEISS) is a set of energetic particle sensors that monitor the charged particle environment at geosynchronous orbit. The SEISS consists of the Energetic Heavy Ion Sensor (EHIS), the Magnetospheric Electron and Proton Sensor (MPS) and the Solar and Galactic Proton Sensor (SGPS).MAGThe Magnetometer (MAG) measures the magnitude and direction of the Earth's magnetic field in three orthogonal directions.  These data provide geomagnetic variations and a map of the space environment that controls charged particle dynamics in the outer region of the magnetosphere.
